Not sure, but probably not. Did you make sure to check “Downconvert DTS-HD to DTS” in tsmuxer? If so, then it’s likely that the mono mix just doesn’t have a DTS core.

It’s actually not possible to create DTS-HD MA tracks that don’t have a core. DTS-HD and DTS-HD MA are extensions to the standard DTS format, and as such, all contain a standard DTS core.

If you want to try a different extraction method, use eac3to. The command line will look like this:

\eac3to “inputfile.dtshd” “outputfile.dts” -core.

If you want to decode it to PCM losslessly, use:

\eac3to “inputfile.dtshd” “output.wav”

Easy peasy 😉

Jedit: Link to eac3to: https://www.videohelp.com/software/eac3to

Just extract to a folder and run under a command prompt, or you can try out the useac3to gui.

The print audio has the correct frequency balance for the soundtrack since it has been recorded through a Dolby A decoder. Most of the laserdisc versions are extremely bright and are too shrill in comparison. However, the print audio is less dynamic than any of the laserdiscs, since stereo optical on 35mm film has very little headroom.

Soundtracks made with Dolby A noise reduction (which includes all the mixes for the Star Wars films except the mono versions) sound much too bright in their undecoded state. It is apparent that none of the early laserdiscs have been Dolby A decoded, hence their excessive high frequency emphasis. The RotJ soundtrack from the Special Widescreen Edition does have the correct frequency balance, so it is likely that it has been Dolby A decoded.

The best possible version of the 35mm stereo mix can be produced by using the early US laserdisc (since it has the most dynamic range) and adjusting its EQ to match the print/SWE versions. That way you get the best of both worlds; the greater dynamics and the correct frequency balance. This is exactly what I did for the 35mm soundtrack on Despecialized v2.5, but I haven’t yet put out one like this that is synced to 4K83.

I will release a track like that at some point soon, but for the moment, I would recommend using the SWE version, because it sounds extremely similar to the print audio, but with better quality.

Do any of the SW '77 stereo mix laserdisc audio tracks have the correct Dolby A-decoded frequency balance as far as you know, or do they all sound similarly over-bright? (As in, any of the pre-JSC remix audio tracks.)

There is only one digital source (technically two) for the '77 stereo mix, the 1986 Japanese Pan & Scan LD release with catalogue number SF098-1103 (as well as the re-release from 1991 with #PILF-1236). I speculated back in August that it may not have had Dolby A decoding applied and worked with a software engineer that I met through the stevehoffman.tv forum to decode it properly using a proprietary Dolby A decoder he was developing. The results were shared over at tswt forums, and my opinion is that it did not exactly work. Overall it was a bit too muffled-sounding. To me the original version was preferable.

My results indicate that it’s probably not as simple as saying that the LD’s are missing Dolby A decoding. While it may be true, there are other possibilities. These mixes were digitized at a time before a DAW would allow for easy manipulation of the audio track, as such, the harshness may be due to the more rudimentary ADC’s being used at the time and a limited ability to deal with tape noise effectively (and SW seems to have a lot of tape noise), or simply the EQ preference of the person doing the transfer. Even if Dolby A decoding is indeed missing, it’s possible (likely?) that the audio was eq’ed to make it more pleasing to the ear. Any sort of eq manipulation would make subsequent Dolby A decoding nearly impossible to perfect.

I was asked by SkyDude to do an improved version of of the 1977 audio for his SkyMaster edition, and I was able to achieve much better results by simply correcting the eq and using spectral noise reduction. I haven’t shared that version, as I was going to let that debut when SkyMaster is released.

It should also be noted that while two “1985 Home Video Mix” files are included in the Alternate Audio folder, they’re actually the same as the 1983 theatrical mix, of which Schorman says the one marked “1983 - Stereo (US Source)” is the best quality.

Thanks, so both the Japan and US ones are from 1985 LD releases? Looking forward to compare them.

It’s not really an alternate. I just posted it individually in case anyone might like to download the track by itself, without the rest of 4K83. I named it “[Cleaned]” because I worked on it, and I don’t want it to be confused with the untouched audio, which I didn’t share, but could if anyone really wanted it.

Thanks, the ac3 file might work better with my blu-ray player. Good to know they’re the same. The main track that I heard when previewing the mkv sounded great.

It would be interesting to hear some comparison samples of before and after your cleanup though. 😃

I was confused. I forgot about the “Alternate Audio” folder. Yeah, that cleaned file is there in case anyone needed it in ac3 format, as ChainsawAsh said.

ChainsawAsh said:

There’s four - two US, two Japan; the ones marked as the 1983 mix are from pan-and-scan LDs, and of those two the US one is the better source. The ones marked 1985 mix are from the Japanese Special Collection and the US Widescreen Edition, which was the debut of the 1985 mix for ANH and (maybe) ESB, but per Schorman, it’s the same mix as the 1983 theatrical mix. They’re presumably only included because whoever made the MKV package (williarob or ohteedee, I think) assumed a new mix was done for ROTJ in 1985, as most of us have for years.

Yeah, I was worried people might be confused by how many different versions there were of the '83 mix. I had them all done so I shared them. In reality, anyone wanting authenticity above all should choose the optical soundtrack. The US pan & scan LD does offer the best sounding version of the soundtrack, in my opinion. The other versions are shared for anyone with an attachment to the JSC or SWE.

Wait, if the optical stereo track included in the mkv is already cleaned up, why is there a separate version in the “alternate audio” folder named “ROTJ - 35mm Optical [Cleaned]”?

It’s not really an alternate. I just posted it individually in case anyone might like to download the track by itself, without the rest of 4K83.

I haven’t finished downloading this yet but I have some questions about the audio. Sorry if they’ve already been clearly answered, I’m too tired to read through the thread at the moment.

What’s the difference between the optical audio track packed in the mkv file and the “cleaned” one?
And are there any digital tracks that actually matches the theatrical stereo audio? I see the 1993 LD track is there but weren’t all the 1993 LD mixes altered? The 1983 Japan and US sources, are they from LDs too?

The image quality is great by the way, managed to preview a bit of it. 😃

Did they color grade the Blu from scratch, though? I thought they used the DVD SE masters as a base, and just fixed some bits and pieces.

In 2004 they scanned in the negatives at 1080p and graded them to that over-saturated-magenta disaster that we’ve been stuck with ever since. There may have been some tweaks in 2011 for the bluray, but the fact remains that all three movies were graded from scratch in 2004.

Having gone through the entire OT and PT frame by frame, when doing my HDTV releases, I can tell you that the only film with significant color changes for the Bluray was Episode II. (Of course TPM was a completely new master. 😉 ) Definitely not re-graded.

My Avisynth-fu has never been anything except rusty, but I think that means if you delete frames 68664 and 68665 from 4k83, you’ll get NTSC GOUT.

That’s right. 😃

Arnied said:
Although I don’t see how there can be 2 extra frames after frame 68663.

It’s the two missing frames of the rebel fleet immediately after Luke’s conversation with Ben. Perhaps you are more used to the PAL GOUT.

What are you trying to re-sync, Arnied?

I want to be able to sync any of schorman’s GOUT synced laserdisc tracks to 4k83. So as I understood it somewhere 2 frames need to be inserted. So I want to duplicate the frame before the 2 extra frames 2 times to get an audio file of the correct length, like in the script above.

However, frame 68663 is already past the wipe, so I don’t think it’s the correct position.

Arnie.d,

I have them all done already. I will be posting them to tswt forums later today or tomorrow.

Edit: Now available!

According to Wikipedia, Williams re-recorded the fanfare for Empire Strikes Back and his version was used in the subsequent Lucas-helmed Star Wars movies.

https://en.wikipedia.org/wiki/20th_Century_Fox

Incidentally, it seems that the “slanted 0” 20th Century Fox logo originally designated Cinemascope as well. Do we know why that particular version of the logo was used in Empire Strikes Back but not SW or ROTJ?

Star Wars has the same logo as Empire. However, some video releases in the 80’s used the updated Fox logo from '81.

Yes, I’ve reached out to him, and have not yet heard back. I’ll post with any further info.

Update: I’ve heard back from the seller, who says he’s unable to sell outside of an auction. It hasn’t been relisted yet, but he says the new listing will start at $299. That still leaves us about $100 short for that price plus shipping.
